To all who: it may concern.

Be 1t known that we, Hinunonn Escooanns'. a-eitizen of the Island of Porto Rico.

and a resident of the borough of Manhattan, in the city of New York, county and State of New York, and FRANClS P. Anruom, a citizen of Spain, and a resident of the borough of Manhattan, in the city of New York, county and State of New Yorlnhave invented a certain new and useful Improvement in \Vrapping-Machines, of whichthe following is a specification.

This invention relates to mechanism for foldingwrappers around articles which are successively passed through the machinei The object of the invention is to simplify such mechanism, and to provide means for wrapping said articles in an efficient manner.

'chanllel. During return movement of said twopart plunger, mechanism foapplying paste to a wrapper flap of a -1' art1ally wrapped article. 111 another one of sa1d reccptacles. aid for folding wrapper flaps of said article in the receiving channel are simultaueously actuated. During the time said chains are moving, wrapper folding mechalusm which is actuated by said means for imparting intermittent movements to said chains, causes said wrapper flaps of the article 1n the receiving channel to be. further folded upon the article. Said means for in parting intermittent movements to said chains also actuate.'rollersfor feeding 1 aper from a supply roll. During the time said feed rollers remain stationary, a wrapper is cut from said papenby means of a. {33,11 of scissorswhich are actuated by a cam formi si PM of h machi n the accompanying drawings: Figure l The invention consists of endless chains is a sectional side elevation of the machine. Fin. 2 is a horizontal section on the line ll-II of Fig. 1. Figs. 3 to 9 inclusive are perspective views showing different stages of folding of the wrapper upon the article. Fig. isa transverse section of the line K--X of Fig. 1. Fig. 11 is a transverse section on the line XI-XI of Fig. 1. Fig. 12 shows the paste applying, and wrapper folding: mechanism, in a. position different from that shown in Fig. 1.

A horizontal driving shaft 1 is journaled in bearings 2 on the frame 3 of the machine. A lever 4 pivoted at 5 on the frame 3. One arm of lever 4- is provided with a roller (3 which engages a cum 7 on shaft 1. The other arm of lever 4 is connected by links 8 to a plunger 9 which adapted for h0riz0ntal reciprocating movement in guides 10.

Secured to shaft 1 is a bevel gear Wheel ii in mesh with a bevel gear wheel 12 which is secured to the lower end of a vertical shaft .J-l. Secured to vertical shaft 13 is a gear wheel 14-. in mesh with a gear wheel. 15 which is journaled upon a-stud shaft 16 extending downward from the frame Forming part of gear wheel 15 is a horizontal disk 17, having an upwardly extending pin 18. During; part of the rotation of gear wheel 15, pin 18 engages one of a series of six slots 19 formed in a horizontal disk 20, which disk is secured to a vertical shaft 21.

During the engagement of pin 18 with any one of the slots 19; the disk 20 and therefore the shaft 21 will moveone-sixth of a revolution. During the time pin 18 is out of engagement with the slots 19. an upwardly extending concentric projection 22 on disk 1'2 will ride against a con *ave surface 23 formed on the edge of disk 20, which will cause the disk 20 and shaft 21 to be held stationary during the time pin 18 is out of engagement with the slots 19.

Secured to vertical shaft 21 is bevel gear wheel which is in mesh with a bevel gear wheel 2:) on a horizontal shaft 26. To the upper end of vertical shaft 21 is secured a bevel gear wheel 27 in mesh with a smaller 7 evident that the intermittent movements imparted to vertical shaft 21 as has been described, will be transmitted to the horizontal shaft 26 by means of the gears 24 and 25, and also to the horizontal shafts 29 and 32, by means of the corresponding gears 2728 and 30-31.

Secured to shaft 32 is a roller 33 and a gear wheel 34. Gearwheel 34 is in mesh 19 with" a gea'r wheel which is secured to a shaft 36. Secured to shaft 36 is a roller 37, the shaft 36 being journaled in movable bearings 38 which are pressed by a spring 39, so that the roller 37 will maintain a yielding pressure against the paper 40 which is passed between the rollers 33 and 37. Said rollers serve to feed the paper downward in a chute.41, and between scissors blades 42 and 43, a distance equal to the length of a wrapper below said scissors blades. It will be evident that this feed of paper will occur only duringrotation of the shaft 21. The stationary scissors blade 42 secured to a fixed rod 44 and the movable 5 blade 43, pivoted upon the rod, is held againstthe stationary blade by means of the The arm 46 of movable blade 43 fi spring 45. is provided with a roller 47 which engages a cam groove 48 formed in a wheel 49 se- 39 cured to the upper end of vertical shaft 13.

The cam groove 48 is so shaped that its action upon the movable scissors blade 43 1S 1 such that after feed rollers 33 and 37 have ceased feeding the paper 40, the cam will cause movement of the blade 43, causing the wrapper blank 50 to be cut from the paper 44). which paper is fed from a supply roll indicated in Fig. 1. The wrapper blank 50, shown by a dotted line in Fig. 1, comes to rest upon supports 51.

Secured to horizontal shaft 26 are chain wheels 52 and 53, over which ride corresponding endless chains "54 and 55. The endless chains 54 and 55 also ride over corresponding chain wheels 56 and 57 which are secured to a horizontal shaft 58.

Between chains 54 and 55 and secured to links thereof-are a series of receptacles 59, for partially wrapped articles, which receptacles are placed at distances apart equal to the amount of travel which is imparted to said chain during each of the intermittent movements of shaft 26. The vertically moving portions of chains 54 and 55, extending from chain wheels 521" 3 to chain wheels 56'-57, travel in guides 60 which are secured to the frame Each end of the receptacles 59, is secured to a single link of chains 54 and 55, and, owing to the fact that said 60 chains travel in the fixed guides 60, the receptacles maintain a uniform position during their vertical travel. The receptacles 59 are each provided with movable walls 61 which are pressed by springs 62, so that the walls maintain a yielding pressure upon with the wrapper flap'72 resting upon a supthe wrapper of an article. The walls 61 are provided with bolts 63 which extend out through walls of the receptacle 59 and nuts 64 fitting the free end of the bolts, serve to limit the inward movement of walls 61 by means of the springs 62.

An article 65 to be wrapped is placed between the plunger 9 and the wrapper blank 50. Forward movement of the plunger will force the article and the wrapper between an upper stationary folder 66 and a lower stationary folder 67, causing the wrapper to be folded upon the article in the manner shown in Fig. 3. The forward movement of plunger 9 is sufiicient to force the article and'partially folded wrapper into a receptacle 59 which is secured to the portions of said chain resting in guides 60, and which travel upward when the movements of said chains occur.

Forming part of plunger-9'is a plunger extension 68, which is in range with a receptacle 59 secured to the portions of said chains resting in guides 60, and which travel downward when the movements of said chains. occur. Plunger extension 68 is xed to plunger 9 by means of an angularly shaped part. 69 which is supported in a guide 70. The forward end of plunger extension 68 is close to said receptacle 59 in range therewith, so that, simultaneous with the forcing of said article and wrapper into a receptacle 59 by forward movement of plunger 9 the plunger extension 68 will travel through said receptacle 59 in range, therewith, and into a-receiving channel 71. After return movement of plunger 9 and plunger extension 68 occurs, the movement of shaft 26 will occur, causing said receptacles 59 to be moved out of range with said plungers, said plungers remaining stationary long enough to permit other receptacles to be moved into range therewith. :During successive movements of said plung s and receptacles, the partially wrapped articles forced into the receptacles which are secured to theportions of chains traveling upward and over chain wheels-52 and 53 will come to rest in the position shown in Fig. 4, and

port 73, as shown in Fig. 1. When this occurs, a paste receptacle 74 secured to arms 75 which are pivoted at-76, is moved from the position shown inFig. 1 to the position shown in Fig. 12. During this movement. a ratchet wheel 77 takes agaihst a spring pressed pawl 78, causing rotation of said ratchet wheel and a shaft 79 to which said ratchet wheel is secured. Shaft 7 9 is journaled in the paste receptacle 74 and has a roller 80 secured to it, which roller revolves in aste 81 within the receptacle and carries sai paste out through an opening 82, so that, when the receptaile occupies the position shown in Fig. 12, paste will be apphed links so to one end of a lever 90 which is piv oted at 91 to the frame 3. The other end of lever 90 is provided with a roller 92 which engages acani groove 93 found in a wheel 94/ on shaft .1. by which it is. actuated,

ll/hen another movement of the receptacle occurs, the wrapper [lap 72 to which paste has been applied will beinoved downwardagainst a stationary folder 95,. causin g said wrapper flap to be folded to the position shown by a dotted line in Fig. l and as-shown in Fig. 5. plunger 0 occurs, the plunger extension 08 Will force the article and" partially folded wrapper out of the receptacle in range, with said plunger cfiitensioinand into the receiv ing channel 71. When this occurs. the p or-. tion of flap 72 projecting: above the article willtake against-tho upper wall 00 of the receiving channel Zl causing the flap 72 to assume the position shown in Fig. 6. It will he evident that the paste 83 on flap 72 will cause the flap to adhere to tl ieportion of wrapper :30 previously folded upon the article. 'l. he forward nnrvement of plung'er extension 68 forces the partially wrap 'ied article to a position where end flaps 07 of the wrapper are in range with downwardly exllatcs'htl are pivoted at tending plates 98! 00 to aihar L00 whiclris secured to the vertically reciprocating -rod S7. The vertical reciprocations of rod 8? occur during return inovement' of the plunger. 'l'he plates 08 are provided with upward cxtensiom 101. and a spring 102 placed lictwecn said extensions forces them outward. causincthe plates 05% to he moved inward toward each other, Plates 98 are curved inwardly, so that as they are moved down by means of vertical rod 87. their outwardly extending lower ends will first fold the flaps 07 around the upper corners of the articleflo. and as the plates move farther down. the inward curvature of said plates will force the wrapper. against the upper corner of the article. said i spring 102 permitting necessary play of the plates outhe pivots 00. Wrapper llaps 102,

of said partially wrap )ed articles in the recciring channel are in range with intermittcntly rotatingfoldo 10! and 10;")- which are sccurial to shaft 00 and llli'inztendina' transversely ahove 'tl receiving: chanmrl.

alsorides over a lar crchain wh .elnlif) so cured to shaft 138. "lhc'chain wheel 110 on shaft 58 is so lJl'OPUI'lZlOlKLl to chain wheel 1.08 on shaft 106 that, when shaft 58 makes Thenas forward movement of range with one of said receptacles during one-sixth of a revolution, one complete revolution of shaft 100 will occur. Secured to shaft 106 is a gear wheel 111 111 mesh with a gear wheel 112 which is secured to shaft 107,.

tions indicated by the arrows shown in Fig.

12. (onsequently. said folders will take against the wrapper flaps 103 of the partially wrapped article shown in Fig. 7, cansing said flaps to he folded to the position shown in Fig.

Repetition of the operation of the machine so far described, will cause articles ha vin their wrappers folded to the position shown in Fig. 8, to he successively moved forward by succeeding partially wrapped articles.

Secured to shaft 100 is a chain whccl 11 over which rides an endless chain l1-lwhich also rides over achain whccl 115 secured t a shaft 110. Shaft 110 extends. through paste reieptacios 117 and has rollers 118 se cured to it. which rollers revolve in paste 1.10 within the receptacles and carry said paste out through opei'iings formed in the bottoms of said receptacles. Secured to shaft 116 is a gear wheel 120 in mesh with a pear wheel 121 whicl is secured to a shaft 21% extending transversely ahovc the receivin channel 71. Secured to shafl segmental surfaces 123. which heinp, rotated lay-shaft and gears 120,-121 from shaft 116, cause paste to he taken from rollers 115w and carried to and deposited upon a wrapper flap 124 of a partially wrapped article in said receivingchannel. as is shown M21555 in Fig. 8. lcceiviugr channel 71 is provided with stationary folders 1213 which. during movement of said partially wrappcl articles in said channel. cause the paste ccatcd wrap-- per flaps 124- to he folded against the wrapped article. in the manner shown in Fig. 0.
